SPECIFICATION forming part of Letters Patent No. 760,498, dated May 24, 1904.

Application filed December 17, 1902. Serial No. 135,650. (No model.)

T0 all whom t TV1/(ty concern:

Be it known that I, WELLINGTON B. TYLER, a citizen of the vUnited States, residing in Driftwood township, in the county of Woods and Territory of Oklahoma, have invented certain new and useful Improvements in Pumps, of which the following' is a specification.

My invention relates to improvements in pumps; and my object is to produce a balanced pump or one requiring approximately the same power to make the up and down stroke of the piston. I attain this object by employing a weight on one side of the piston and a column of water on its opposite side, so that instead of exerting all the power on either of the strokes it is divided between them, and consequently the act of pumping will be performed with the least possible exertion.

The invention may also be said to consist in the novel construction, arrangement, and combination of parts. hereinafter described, and pointed out in the claims, and in order that it may be fully understood reference will now be made to the accompanying drawings, in Which- Figure 1 represents a vertical sectionalview of my improved pump. Eig. 2 is a detail plan view of a disk forming part of the valved piston. Fig. 3 is a broken vertical sectional view of the valved piston, taken on line III III of Fig. 2. Fig. 4 is a vertical sectional view of the lowerportion of the gooseneck tubing, showing the valved piston in position to allow the water in the upper portion of said tubing to settle down below the freezingpoint.

In constructing my invention I employ a gooseneck tubing comprising a lower cylinder 1, having a iiaring opening 2 at its upper end and communicating at its lower end with a smaller cylinder 3, connected at its lower portion by a U-shaped portion 4 to a barrel 5 of the pump. Said barrel is provided at its upper portion with a spout 6 for the discharge of water and a hand-lever 7, fulcrumed at its forward end to a bracket 8, secured to a cap 9, which closes the top of the barrel against the entrance of dust, 6to.

10 indicates a vertically-arranged piston-rod V pivotally secured at its upper end to the handlever and extending down through cylinder 1 into the smaller cylinder 3.

11 indicates a disk rigidly secured to the piston-rod and adapted to snugly iit in cylinder 1. Said disk is provided with apertures 12 for the passage of water and in conjunction with a float 13 forms a valved piston for forcing water from the cylinder and pump-barrel out through the discharge-spout 6. Float 13 is cylindrical in form and is rendered buoyant by an air-chamber 111, and as it is of less diameter than the bore of cylinder l and slidably secured upon the pistonrod it is normally held in contact with the lower surface of the disk by the water in the cylinder. he joint between the disk and {ioat is made water-tight by a Washer 15, secured to the top of the latter, and as the float and washer are of suITicient diameter to close the openings in the disk it is apparent that on the downward stroke of the piston-rod the disk will contact with the float, and as they move downward together they will force the water from cylinder 1 down into the smaller cylinder 3. As the water is forced from cylinder l into cylinder 3 it passes through a discharge-valve located therein and secured to the lower portion of the piston-rod, upon which it is retained by a nut 16. The discharge-valve consists of an apertured disk 17, snugly fitting in cylinder 3 and rigidly secured to the piston-rod, and a cylindrical float 18, provided at its top with a suitable washer 19, and is slidably mounted upon the piston-rod, said discharge-valve being similar in construction to the valved piston, with the exception that it is smaller in diameter to tit within the small cylinder 3.

20 indicates a weight secured by a set-screw 21 to the piston-rod to assist the operator in forcing the piston on its downward stroke.

i In starting the piston on its downward stroke {ioat 13 will be held in contact with disk 12 by pressure of the water within the cylinder 1, and asthe area of said cylinder is greater than the area of cylinder 3 the water as it is forced into the latter depresses float 18 below its seat against disk 17 and escapes through the apertures therein into the pump-barrel,

ton.

where it is elevated and discharged through spout 6 by successive strokes ofthe valved piswell it is obvious that the weight of said column bearing against the lower side of the discharge-valve will materially assist the upward stroke of the piston, and by employing weight 20 to assist the downward stroke of the piston the power required to make both strokes may be made equal. vBy utilizing the water column in the pump-barrel and weight 20 to assist in making the up and down strokes it is obvious that the pump can be operated with greater ease than if the column oi' water was sustained without the assistance of the weight, and by equalizing the power required to make both strokes the 'pump is rendered especially adaptable for use in conjunction with windmills, Sac., which work to better advantage with a steady load.

During freezing temperature the water column within the pump-barrel may be allowed to recede to a level with the water in the well by elevating the rear end of the hand-lever sufiiciently to raise disk ll up into the flaring' top of cylinder l, so the water may'fiow therefrom'into the well. t y

By permitting the water to flow back into the well through the top of the cylinder instead of allowing it to discharge against the side of the well through a small aperture in the pump-barrel it is obvious that all danger is avoided of caving in the wall of the well when it is not lined with brick or stone.

From the above description it is apparent that I have produced a pump which is simple in construction, thoroughly effective for the purpose intended, and which may be modified in some particulars without departing from the principle of construction involved.`

Having thus described my invention, what I claim, and desire to secure by Letters Patent, isf l. In a pump, a gooseneck tubing comprising a barrel provided atits upper portion with a discharge-spout, a cylinder smaller Vin diameter than the barrel and connected to the lower end of the same by a U-shaped portion, a cylinder approximating the diameter of the barrel and connected at its lower portion tothe When the valved piston makes its up-A upper portion of the small cylinder, a valved piston reciprocably arranged in the cylinders.
